Recently a bug was discovered in the MailCOPA email client SPAM white list. The documentation states that you can add an entire domain to the whitelist by adding *@filecopa.com for example. Unfortunately in the current release this is not functioning correcty.
The bug has been fixed, but is not currently in a public release. If you are experiencing difficulties with this then please email our support desk at firstname.lastname@example.org and ask for details to the latest test build.
